Diodes - Rectifiers - Single - DLM10E-AT1 Application Field and Working Principle

DLM10E-AT1 is a single-phase bridge rectifier and is part of the DLM series of rectifiers. The DLM Series is designed for use in a wide range of electrical and electronic circuits, for use with AC and DC power supplies, for power conversion, variable speed drives and control, switching, and other power control applications.

The DLM Series includes three main types of rectifiers; Diode, Bridge, and Combination. The Diode type rectifier consists of only two diodes, while the Bridge type consists of four diodes arranged in a bridge configuration. The Combination type is basically a combination of the Diode and Bridge type.

DLM10E-AT1 is a bridge rectifier, with each leg of the bridge consisting of two diodes. The anode of the first diode on each leg is connected to a common positive terminal, while the cathode of the second diode on each leg is connected to a negative terminal. When AC power is connected at the common positive terminal, the two-diode combination provides a low-resistance path for current to flow from the positive terminal to the negative terminal.

The main advantage of using a bridge rectifier is that it can rectify both the positive and negative alternations of the input AC voltage. This means that the rectified DC output voltage is always of the same polarity. Another benefit is that the bridge rectifier also provides a higher degree of electrical isolation between its input and output terminals, allowing for safer operation. The output voltage is slightly lower than the input AC voltage, but can be easily regulated with the addition of a filter capacitor.

The DLM10E-AT1 bridge rectifier has a peak forward voltage of 10 volts and a continuous forward current rating of 10 amps. Its maximum reverse voltage capability is 50 volts and its peak reverse current is 1.5 amperes. It is usually used in applications where a high forward current, a low voltage drop, and/or electrical isolation between input and output are required. The DLM10E-AT1 is a low-cost and reliable solution for many AC/DC conversion applications.

In summary, the DLM10E-AT1 bridge rectifier is part of the DLM series of rectifiers used for AC to DC conversions. It is useful in applications requiring high forward current, low voltage drop, and/or electrical isolation. The four-diode bridge configuration rectifies both positive and negative alternations of the AC voltage, providing an output voltage similar to the input voltage. It is a low-cost and reliable solution for most AC/DC conversion applications.
